Because we know how quickly lung cancer can grow, we should be able to annually screen people who have a high risk of lung cancer. And this should be done over a period of 20-25 years. But this is demanding for the people themselves, as well as the healthcare system. We believe that, after the first CT scan, we will be able to effectively assess whether it is possible to wait slightly longer until the next scan. For example, 2 years instead of 1 year.
The population screening study is focusing specifically on people whose first CT scan showed no indications of lung cancer. For approximately 9 in 10 people, no indications of lung cancer a found during the first CT scan. We would like to know whether it is equally safe to invite this group of people for a CT scan every 2 years instead of every year. This will greatly reduce the number of examinations, and thus also the disadvantages experienced by the people themselves.
